Increases or declines of any quantity at a 10-percent rate are serious matters. If anything grows at 10 percent annually, it doubles in 10 years. If something declines at a 10-percent annual rate, it disappears in 10 years.
It’s something to ponder seriously: Sowmyanarayan Sampath, Verizon Communications SVP of transformation says Verizon’s copper-based revenue is declining eight percent to 10 percent a year.
At that rate, the revenue stream disappears in a decade. If you want to know why tier-one telcos want to decommission the old “public switched telephone network,” that is why.
